Brillouin Scattering Studies of the Effect of Orientation on the Mechanically Deformed Poly-(Ethylene Terepthalate),
Abstract
Brillouin light scattering is used to study the internal structure of oriented films of poly(ethylene-Terepthalate). Brillouin scattering was observed to occur independently from the crystalline and amorphous regions in the superstructure. Sound velocity data from these two regions are used to draw directional maps of the sound velocity in the films and are shown to give structural information for both regions. The results are discussed qualitatively and correlated with a recently proposed model. The amorphous phase orientation distribution functions are calculated for a series of draw ratios using the hypersonic velocities. The results are in agreement with published results which were obtained by a different method.
